I have one and can't answer why they are for sales except that people willing to pay several thousand for one may be looking at other high players. There have been some problems with the software which are resolved by this time and a simple upload can handle. Also the slide drawer on earlier models had some problems which are repaired by the company, but has not been an issue for some time. The unit is fantastic otherwise. It is upgradeable and you should look at the madrigal website for a full description.
